Be it known that i, ALLEN Bowers, a citizen of the United States, resding at Fort .lVavne in the count of Allen andState of 9 a idiana haveinvented certain new and use- It ful Ilium-0v ts in Sepei tor-Tanks, of

which the following is a specification,

'llhisinveution relates to improvements in separator tat-nitsparticularly adopted for use ingarages or similar pieces and the primarymeans for causing the watcnto accumulate inthe tank to permit t oil-andgrease to separate .tnerefron'i; and improved means for preventing thedischarge of the Water when a predetermined smount'of oil and grease hasaccumulated inithe A further object; is toprovide improved means forpreventing the incoming Water from passing-directly out: of thedischargepipc before the oil and-grease is separated therefrom, and.improved means for with 1 drawing the oil and grease from the tank.

Aiurt-her object' tQ'PIQVldG en 1m proved device of th s'chnracter wh chwill be sin1ple,'cheap and durable inconstruction and eliici'ent andeffective in operation;

To the etteimnentoftliese ends :indthe' accomplishment of other newenduseful objects, as will appear, the invention consists in thefeatures of novelty in the construc-' tion, combination anderrangementof the several parts hereinafter more fully de' scribed andclaimed and shown in the.aceoinpanying drawing, illustrating. anexemplification of theinvention end inwhich-e Figure 1 is a longitudinalsectional view of an improved tank of this character con-" structed inaccordance with the principles of this invention. Fig. 2'is a sectionalView on line 2--2 of Fig. 1.

Referring more particularly to the drawing and in this exemplificationof the invention, the numeral 10 designates a closed tank of any desiredsize and configuration.

and constructed of any meterialjsuitable for the purpose. This tank isprovided with an 1 "which latterjis inlet opening 1-1, located in theside preferably adjacent the} bottom thereof, amanhole 12 and a suitablevent opening 13, preferably located in the top of the tank;

Within the tank is a suitable housing or tubular member 14, which isprovided with a. flat bottom adopted to rest upon the bottom of thetank. Tl'iis'housing or member 14 is also provided with an inlet opening15 and an outlet. 16 locatedin the upper face or wall thereof and bothof said openings 15.

and 16 are preferably provided with interior screw threads. A suitablebushing 17 pro vided with exterior screw threads is seated Within theopening 15 so that the threads thereon will engage the threads in theopening to prevent displacement of the bushing and suid bushing. forms aseat for a suitable valve 18, which latter is adapted't-o close theinlet opening 15 of the housing or tubular member 14" "when the valve isseated upon thebusl1ing-l7, 'as shown invdotted lines in 1;Xt'endmgtlniough the side of the'tank is a discharge pipe or, nozzle 19,which is preferably provided with a projecting flange 20, adapted tocover the opening 21' in the side of the tank through which the pipe ornozzle 19 projects and said pipe or nozzle is securely held in positionin any desired or suitable manner. The portion of the-pipe or nozzle 19which projects inside of the tanlqpreferablytapers toward the extremitythereof, as shown more clearly at 22 in Fig. 2 (lithe-drawing, and saidtapering extremity 1s. provided with an opening 23in the lower facethereof. This opening 15' preferably of a diameter equal to thediameter-of the outlet opening 16 ofithe tubular member or housing 14,and said openings 23 and 16 are spacedfrom eachother and arranged inregistering position with relation to each other. The pipe or nozzle 19may be arranged at any desired point in the height of the tankaccordingto the height that it is desired to maintain the Water level asindicated at 2 1. The outlet opening 25' of the pipe or nozzle may be ofany desired configuration and to said nozzle adapted to'be coupled orsecured any suitable discharge pipe not-shown) for conve in the water asit )as'ses'from'the tank to the sewer trap or pipe. A suitable tubularmember 26 is preferably provided tubular member 26 is .or nozzle 19after the sleeve or with peripheral screw threads adjacent theextremities thereof and said-tubular member is preferably of an"exterior diameter slightly sniltller than the interior diameter of theopenings 16 and 23 respectively of the tubular member or housing 14; andthe discl'iarge pipeor nozzle 19. One extremity of the tubular member 26is adapted to be seated within the outlet opening of the housing ormember 14 in such a manner that the screw threads on said extremity willengage the threads in the opening 16 and said tubular member is of sucha length that the other extremity thereof Will standadjacent to theopening 23 in the pipe or nozzle 19. A suitable collar or sleeve 27 isprovided with interior threads adapted to engage the exterior threads onthe free extremity of the tubular member 26 and said sleeve or collar.27 is adapted to be secured to the pipe or nozzle 19 for holding theextremity of the tubular member 26 in registration with the opening 23in any desired or suitable manner, such as by means of screws or bolts28 passing through the sleeve or collar 27 and into the adjacent portionof the pipe or nozzle 19.

In constructing this tank, one end of the secured to the housing ormember 14 and the free extremity thereof is placed adjacent the opening23 in the pipe collar 27 has been placed upon said extremity. When inthis position, the sleeve or collar 27 may be screwed or adjusted uponthe extremity of the tubular member 26 until it engages the face of lhepipe or nozzle 19, and a further adj ustmeht of the sleeve or collar 27against the facelvti'f the pipe or nozzle 19 will exert an endwisepressure upon the tubular member 36 to force the housing or membeitllagainst the bottom of the tank to hold the housing or member 14 againstdisplacement. After the desired pressure has been obtained, the sleeveor collar may be secured against further movement by means of the screwsor bolts 28. A suitable support or fulcrum 9-9 is arranged upon thhousing orm'ember 1-1- adjacent the inlet opening 15 and a lever 30 ispivotally supported utter-mediate its ends by thefulcrum fine end ofthis lever isconnected as at 3]. to the val re ,18 and pivotally conne.id to the free end of the lever is abar' or member 32, which extendsupwardly toward and terminates short of the top of the tank, andsupported by the free end thereof is a suitable float A suitable guide34 is provided for the bar or member 32 and said guide is preferablyS21?" '--"!ll (l by the pipe or nozzle 19.

Li-ranged within the tank 10 and extendtransversely of the tank is apartition 35, which of any desired height to extend above he tubularmember or housing 14 and i used between the housing or member oil andgrease must. be

.the den tubular member or housing i l and out .1

14 and the inlet opening 11 of the tank. This partition 35 is preferablyspaced from the inlet opening 11 and serves as a means for preventingthe formation of an eddy as" the water enters the pipe and prevents the7( water from passing directly into the inlet opening 15 of the tubularmember or housing 1t and causes the water to-accnmulate in the tank.

A plurality of apertures or openings 36 are arranged in the side of thetank and secured to the tank adjacent each of the apertures 3G is a stopcock 3?, and said stop rocks are for the purpose of withdrawing the oiland grease from the tank which has accumulated on the top of the water.

In ,use, the water passing from the catch basin enters the tank throughthe inlet open ing 11 and as the discharge inlet of the pipe or nozzle19 is located at some distance above 35 the bottom of the tank, theincoming water will strike the partition 35 and will accn mulate in thetank until the water level 2a is reached. The weight of the neat" 33,together with will cause the valve 18 to remain unseated. As the water,together with the oil and grease, accumulates in the tank, the oil andgrease will separate itself from the water by thereof and will aecuinu-9 the water, after which it the tank by the stop passing to the top lateupon the top of may be drawn from cocks 37. If it should so happen that.the tank is neglected and the oil and grease is not drawn from the topof the water but allowed to ac- -1nnulate inthe tank, the float will beraised by the accumulation of theoil and grease above the Water leveland by raising the lloat the valve 18 will be closed, which will causethe incoming water to accumulate in the feed pipe and also in the catchbasin, from which the operator will knon that l the drawn from the tank,otherwise it will be forced into the sewer pipe or trap. A fter the oiland grease-has been withdrawn by means of the cooks 3'2, 33 will descendand open the valve water to pass through.

l8 to pern'iit the through the discharge pipe or nozzle 19.
